400,000,000,200,000,000

Explanation:

First you need to start with

500,000,000 x 800,000,000

this is because multiplication always comes first even if its not at the start of the equation.

500,000,000 x 800,000,000= 400,000,000,000,000,000

Then add 200,000,000

An easy way to do this is line them up like this:

400,000,000,000,000,000

200,000,000

then put the 200,000,000 in where it lines up

400,000,000,200,000,000
